Title: Improvements in and relating to automatic curve-following apparatus
Inventor: SYKES NEIL WINN
IPC: G06K11/04
Filed: 1954-03-12
Abstract: 759,868. Automatic curve following ap paratus. ENGLISH ELECTRIC CO., Ltd. March 11, 1955 [March 12, 1954], No. 7259/54. Class 40(1) [Also in Group XL(b)] The invention relates to automatic curve following apparatus of the type described in Specification, 690,426 wherein a cyclical scanning device 1 scans a curve 2, which may be a line, as in Fig. 1, or the edge of an area, as in Fig. 2 so that photoelectric detection apparatus causes electric pulses to be produced when the line or edge 2 is crossed, the spacing of such pulses being used to operate circuits controlling servo mechanism, which guides the scanner device along the line. In such apparatus, the follower is arranged to follow a curve in response to a resolved component along a reference axis x or y of an instantaneous error distance between the actual position of said follower and a required position on said curve, and is characterized according to the invention, in that said resolved component is obtained automatically from information contained in a wave form of an electrical signal derived from a cyclically operating scanning device by computer means which are arranged to respond to the phase displacements between a reference position in the wave form and two characteristics in the wave form which indicate the two interceptions per cycle between the scanning path of said scanning device and the curve, said scanning device and the curve, said computer means serving to produce two signals respectively proportional to the cosines of said two phase displacements and serving to add these two signals to produce an output which is a measure' of the resolved component of said error distance 'along said reference axis, which is an axis related to said reference position. The apparatus operates on the principle that the error distance e may be resolved into parts # Sin # and # Cos # and introduces corrective components #dx/t# = Vcos#-g # Sm# and #y/#t = VSin#+ ge Cos# into the drive of the scanning head (V being the speed of the scanning head and "g" a suitable conetant). Figs. 1-3 represent diagramatically the scanning device which produces pulses when the edge 2 is crossed at the points A and B as indicated in Fig. 4. Such pulses are fed to a control circuit as shown in Fig. 7, wherein the function of the first part, above the dotted line, is to separate the pulses corresponding to intersection A from those corresponding to intersection B and the function of the other part, below the dotted line, is to convert the wave form of the separated pulses into some form which will be appropriate to give a control as indicated above, the wave forms marked being converted by electronic gate and clamp units 6.

Title: Improvements in piston and piston rings
IPC: F16J9/04
Filed: 1926-03-17
Abstract: 256,885. Kottusch, E. March 17, 1926. Pistons; packing. - A piston packing-ring adapted to prevent piston slap and distribute oil consists of a helical ring the turns of which are in contact at the upper end and gradually separate towards the lower end. The ring is formed by cutting a slot 8, Fig. 3, in a cylindrical blank and making axial cuts 11<a>, 13. The upper end of the blank has a helical surface, so that, when the ring is compressed axially the upper turn comes into contact with the adjacent turn. As shown in dotted lines, a piece is cut from the end of the upper turn, while the end of the lowest turn enters a recess cut in the cylindrical part of the blank. The upper end of the ring may be formed with an internal flange 15, Fig. 5, engaging a groove in the piston. In this case the lower piston flange 6 is formed with a slot 17 to enable the packing to be screwed into position.

Filed: 1926-03-23
Abstract: 258,217. Rheinische Textilfabriken Akt.-Ges., and Brock, G. Sept. 12, 1925, [Convention date]. Pile fabrics; figured fabrics. - A woven Gobelin fabric having coloured wefts, a ground warp a, Figs. 7 and 8, and binding warps b, c is provided with a frise effect formed by a looped pile warp d, thus producing a pattern additional to that formed by the coloured wefts. Three fast picks e<1>, f<1>, g<1> or e<2>, f<2>, g<2> &c. and two loose picks h<1>, i<1> or h<2>, i<2> &c. are used in succession, the loose picks being inserted some distance from the finished fabric so as to produce the pile loops at the beat up, the weaving being as shown. The weaving of an ordinary Gobelin fabric and of an ordinary jacquard fabric are also described. According to the Specification as open to inspection under Sect. 91 (3) (a) the frise patterning is produced by using a tensioned ground warp and a loose pile warp, inserting two 'wefts at a distance from the fell of the fabric, and then a third weft with which the pile warp is interwoven, the three picks being finally beaten up to the fell of the fabric to form terry pile. The pile may be raised to varying heights and the higher pile may be cut so as to give a velvet effect. This subject-matter does not appear in the Specification as accepted.

Abstract: 678,737. Magnetic separators. SIMONCARVES, Ltd., SYMINGTON, R., and CLEAT. L. H. March 29, 1951 [April 4, 1950], No. 8457/50. Class 72 In a magnetic separator for liquids, a magnet is arranged to produce a strong localized field near the surface of the liquid in a settling tank, and a moving collector under the pole faces carries the magnetized particles out of the field to a position where they can settle to the bottom of the tank. As shown, the liquid is fed in through a pipe 6 and a magnet 11 causes the magnetic material to agglomerate on the collecting disc 13, which is rotated by a motor 17 through gearing 18. Radial vanes on the underside of the disc carry the agglomerated material out of the field, when it sinks ,and is drawn off through the pipe 22. Non-magnetic material is carried under the wall 2 and over the weir 20 by the flow of liquid and is extracted by the pipe 21. Water may also be introduced into the tank through the pipe 24 to provide an upward current to prevent settling of non- magnetic particles.

Fig. 1 shows the wheel hub 10 which carries wheel discs stiffened by spokes 15 supporting a load-bearing rim 16 which rolls on the articulated track 22. To each of the articulations 29 are pivoted a short link 31 and a long link 32. The inner ends of the short links are pivoted to rocker arms 33 and the inner ends of the long links are pivoted to rocker arms 34. Fig. 3 shows half the wheel in cross-section.

Abstract: 435,409. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. March 20, 1934, No. 8732. Convention date, March 23, 1933. [Class 40 (iv)] In a system in which low-frequency alternating current is employed for transmitting impulses between exchanges, the impulse repeating relay is connected in series with an element of a high-pass filter included in the speech circuit. As shown, Fig. 2, A.C. signals from the junction FL3 are repeated as D.C. impulses by IR3, the first digit operating the stepping magnet GM1 and subsequent digits, when an idle junction FL4 has been seized, operating relay R3 in the junction circuit to repeat them as A.C. impulses over the junction. Signals in the opposite direction are similarly repeated by IR4 and R2. The relays R2, R3 short-circuit the relays IR3, IR4 respectively. Rectifiers KL1, KL2 prevent wrong operation of R2, R3 by inductive kicks. The A.C. signals are prevented from passing through the talking circuit by the network S1, S2, C1, C2 which forms a high-pass filter. In a modification, Fig. 3 (not shown), the network is wholly in the selector circuit and the D.C. impulses are repeated by the A.C. responsive relays over the two wires of the talking circuit in parallel, the impulse circuit being connected to the mid-point of the choke corresponding to S2 and to the mid-point of a resistance bridged across the talking wires of the junction circuit. In a further modification, Fig. 4, A.C. impulses from FL7 are repeated as loop interruptions over L4 and loop interruptions at the far end of L4 are repeated as A.C. impulses over FL7. The A.C. responsive relay IR7 controls a repeating relay R10, R8 having been energized initially over the loop. The first impulse of each digit energizes R9 which remains energized throughout the digit, substitutes a non- inductive bridge for R8 and completes the local impulse circuit independently of the latter. Impulses (interruptions) in the other direction are repeated by R8 (R7 remaining energized) to R6 which repeats them in A.C. form over FL7. The line L4 may be a trunk to a local switch.
